Matlab File

%read and play the extract
data = wavread('jpforward.wav');
wavplay(data, 44100);
%reverse the 'data' of the extract
reversed = flipud(data);
%put the new data into a file
wavwrite(reversed, 44100, 32, 'jpbackward.wav');
%read and play the new file
reversed_data = wavread('jpbackward.wav');
wavplay(reversed_data, 44100);
%play the new file, but with half the speed
wavplay(reversed_data, 0.5*44100);


I really can't catch what the singer says, even when I try reverse the extract. However, in the reversed extract, my best guess would be that the singer says "just free your mind".
